If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Move the fan with the mouse, so that the balloon can move in the right direction. The goal of the game is to find the greatest amount of stars possible. For each star you will win between 5 and 24 points. Let the butterflies and the bats go by, in this way you will not loose your points. Also you must be careful with birds, if you touch them, your balloon can explode.
Use mouse to move the fan.
